Lewis and Clark Caverns

Lewis and Clark Caverns State Park, Montana

This post may contain compensated links. Find more info in my disclaimer.
Montana’s first state park is a showstopper. Stalactites, stalagmites, columns and cave bacon decorate this large limestone cave. A two-hour guided tour takes visitors through two miles of walkable cave trail.
Personally, I prefer natural lighting to colored lights, but maybe you’ll think it’s fun and festive. The cave is highly decorated and well worth a peek.
Cave tours are available May – September with a few special tours during the winter holidays. 


While the cave is the main event, there is more to Lewis and Clark Caverns State Park.

  • Trails to wander on foot or bike year round
  • a state-of-the-art visitor center with interpretive displays to help the whole family learn about the park—both above and below ground
  • gift shop
  • food and beverage concessions
  • picnic areas
  • amphitheater
  • a large campground with showers, and a tipi, and three cabins
  • interpretive events in summer

If it’s a warm day, head down to the Jefferson River to wade and cool down.

Henry calls this the “practice cave.” It’s in the upper Visitor Center (yes, there are two).
